AUTOMATIC BASF-LATCH.

Application med August .23, 191s.

To allfwhom it may concern:

Be it known that we, LOUIS B. GoLDBERG and NATHAN GOLDBERG, citizens of the United States residin at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Automatic Hasp-Latches; and we do declare the following to be a full5 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make Vand use the same, reference being had to the accompanyino' drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to hasps and constitutes a latch or retainer to automatically engage a4 stud or like member projecting.`

in the hasp to retain the position. l invention is designed particularly for use on shipping cases for motion picture films, and the object is the provision of a device which will positively and automatically secure the hasp when it is moved to closed positiomwithout the use ofa separate member such as a padlock or snaphook. Commonly the film case is closed merely by passing the eye of the hasp over a pivoted headed stud and then turning the head at an angle. But since no further means is used, the head frequently will turnback through handling of the case until the head is in alinement with the eye, so that sudden movemen of the case will cause the hasp to ily olf the Stud, with the result that the lid swings open and the film-roll falls out.

It is very desirable therefore to have a simple and preferably automatic means on the hasp that will secure the hasp against ac cidental movement from the stud. This invention provides such a means which assumes its operative position as soon as the hasp is positioned, and may be readily withdrawn to release the hasp. Briefly it comprises a plate slidable on the hasp and spring pressed to cause it to assume operative position, the forward end of the plate being adapted to engage the head of a stud. Thestud has a sloping portion to guide and retract the slide as the hasp moves to operative position and has a lower shoulder to engage and retain the sliding plate. ln the drawings:

The shipping case A has a pivotally mounted headed stud 10 thereon and the hinged lid B of the case has a hasp 20 hinged thereto, the hasp carrying a slidably mounted spring-controlled latch plate 30.;

The stud 10, pivotallymounted in the case at 11, has ahead 12, the upper portion 13 of which is rounded or sloped while` portion is in the form of a shoulder 14. An aperture 15 for the reception of the bail of a padlock may be provided if desired.

The hasp 20 has the usual longitudinally extending eye 21v tok receive Vthe stud 10. hasp is provided atits forward end with a pair of Struck up lugs 22 to limit the forward motion of the latch plate 30, and at an intermediate point with a pair of ugs 23 to engage the ends of the springs 31 for cornpression of the same. -The springs 31 are mounted in channels in the under face of the latch plate extending longitudinally thereof,v corresponding upstanding ribs 33 being formed on the outer face of the plate. These ribs, when the latch is in operative position, extend along both sides of the eye 21 of the hasp. The forward end of the latch has a slot 34C therein so that the sides of the latch plate adj acent the Slot 311 will pass along the sides of the ystud when moving into operative position. At the inner end of the slot the latch plate is rolled up slightly at 35 to provide a surface which will ride smoothly on the rounded portion 13 of the stud head 100 10 is positioned to eo y the underv The so 21 and the hasp then swung 1710 ed edge engages the rounded sloping and a hasp having an eye therein ior the face 13 with the result that, as the hasp reception of the stud of a spring-actuated continues to move down, the latch plate is plate, slidable on the outer face of the hasp down to pass over the stud, whereupon the 2.
